1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundDisuse is a cardinal sign of various neurological diseases like stroke, cerebral palsy, and amyotrophic lateral sclerosis. Disuse leads to reduced mechanical loading of the skeleton, and a substantial and significant loss of bone mass quickly materializes. Several animal models have been proposed to investigate the pathogenesis of disuse-induced bone loss and to test new pharmaceutical targets to counteract it. As animal models may overcome several of the limitations in observational studies conducted in patients and allow for measurements not possible in humans, the primary objective of the present study is to provide a comprehensive overview of the available animal models of disuse-induced bone loss. METHODS/

designThis is a protocol for a systematic review of animal models of disuse-induced bone loss. An exhaustive search will be performed on PubMed and Embase in order to identify relevant studies. The primary outcome will be the method of disuse induction. The secondary outcomes will be related to bone samples and anatomical sites investigated, methods used to analyze and quantify bone loss, and bibliographic information. The protocol adheres to the current guiding principles of the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) 2015 statement. Extracted data will be analyzed with descriptive statistics, and all the methods used to induce disuse will be described in detail with a narrative synthesis. DISCUSSION: This systematic review will provide an overview of available animal models of disuse-induced bone loss and discuss the different methods used to quantify and analyze the bone loss. Since bone loss caused by disuse is a hallmark of various diseases from different medical specialties, this overview will be of great benefit for all researchers planning to conduct disuse animal studies in the future.
